我按照https://cloud.google.com/sdk/docs/quickstart-debian-ubuntu下载了Google Cloud SDK。 我通过以下 https://github.com/GoogleCloudPlatform/python-docs-samples/tree/master/speech/cloud-client下载了Google Speech API。 当我运行python transcribe.py resources/audio.raw， 时会发生错误。我得到一个错误，TransportError：HTTPSConnectionPool（host ='accounts.google.com'，port = 443）：最大重试次数超过url：/ o/oauth2/token（由SSLError引起（SSLError（1，u'[SSL ：CERTIFICATE_VERIFY_FAILED]证书验证失败（_ssl.c：581）'），）） ）>）TransportError：HTTPSConnectionPool

)>)我安装模块可用于HTTPS到Ubuntu ，所以我真的不明白为什么会出现这样的错误。Google Cloud API的认证没问题，所以我d o不知道这是什么样的错误。我应该如何解决这个问题？
